ELECTROMEDICAL BELT.

SPECIFICATION forming part of Letters Patent No. 721,032, dated February17, 1903.

Application filed November 29,1902. Serial No. 13 8,210. (No model.)

To all whom it may concern.-

Beit known that I, FRANK FARMER, a citizen of the United States,residing at Richmond, in the county of Wayne and State of Indiana, haveinvented new and useful Improvements in Electromedical Belts, of whichthe following is a specification.

My invention relates to new and useful improvements in electromedicalbelts, and more especially to the battery used in connection therewith;and its object is to provide a cell of novel construction having meanswherebyv the binding-posts thereon may be covered, and thereby preventedfrom injuring the body of the wearer.

Another object is to employ means for securely fastening the parts ofthe cell together.

iWith the above and other objects in view the invention consists in thenovel construction and combination of parts hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings,showing the preferred form of my invention, and in Which- Figure 1 is anelevation of a medical belt having my improved cell connected thereto,and Fig. 2 is a vertical transverse section through the cell.

Referring to the figures by numerals of reference, 1 is a fiat andsubstantially rectangular cell having its edges rounded to presentsmooth surfaces to the body of the wearer. This cell is preferablyformed of hard rubber and is provided inside with battery-plates 2 orother suitable means for producing electricity. A cover is fitted snuglywithin the top of the cell, and a soft rubber washer 4l is preferablyinterposed therebetween to form an air-tight joint. The binding-posts 5of the battery are detachably iitted in the cover 3, preferably nearopposite ends thereof, andr are connected, respectively, to the positiveand negative plates 2 Within the cell by means of wires 6. These postsare screw-threaded and extend above the cover 3, and each is `providedWith a nut 7, which serves to bind to the post a hooked strip8,-arranged longitudinally upon the cover and extending adjacent to theend thereof. Each hook is adapted to be engaged by the looped end of awire 9, and these wires are connected to positive and negative plates ordisks 10, arranged adj ustably upon a belt 11.

A cap 12 is adapted to be secured upon the cover 3 and shield the bodyof the wearer from contact with the binding-posts, hooks, and ends ofthe wires. This cap is recessed longitudinally in its bottom surface ateach end, as shown at 13, such recesses being of sufficient depth toreceive the heads of the posts 5, the hooks 8, and the ends of the Wiressecured to said hooks. The nuts 7 are round and iit snugly withincylindrical recesses 14, extending inward transversely of the recesses13, and these nuts therefore serve to retain the cap in proper positionupon the cover'. A recess 15 is formed in the top of the cap 12, and asimilar one, 16, is in the bottom of the cell. These recesses have theiredges rounded and are adapted to receive an elastic strap 17, having abuckle 18 or other means for securing it within the recesses and bindingthe cap upon the cell.

It will be seen that the cell is extremely simple in construction, andall rough or uneven parts thereof are located out of contact with thebody of the wearer.

, In the foregoing description I have shown i the'cap to the cell.

2. In an electric battery,a cell having binding-posts extendingtherefrom,hooks secured to said posts, a recessed cap upon the cell, therecesses of said cap being adapted to receive the posts and hookswhereby lateral displacement of the cap is prevented,and means forsecuring the cap to the cell.

3. In an electric batterya cell having arecessed bottom,a cover tted onsaid cell,bind ing-posts extending from the cover, hooks se- IOS) curedto the posts, a, cap having a recess in the top thereof and recesses inits bottom face, said bottom recesses being adapted to receive the postsand hooks and the ends of wires secured to the hooks, whereby lateraldisplacement of the cap is prevented, and a strap Within the recess ofthe cell-bottom and the top recess of the cap and adapted to bind saidcell and cap together.

4:. In an electromedicel belt the combination with a, belt, platesthereon and wires eX- tending therefrom, of a battery-cell having arecessed bottom, a cover fitted on said cell, binding-posts extendingfrom the cover,hooks secured to the posts, a cap having a recess in thetop thereof and. recesses in its bottom face, said bottom recesses beingadapted to receive the posts and hooks and the ends of wires secured tothe hooks, whereby lateral displacement of the cap is prevented, and aFRANK FARMER.
